mineral wool

[′min·rəl ¦wu̇l]

(materials)

A fibrous substance, technically a glass, made from molten slag, rock, glass, or a selected combination of these ingredients; produced by blowing, drawing, or other means of fabricating into fine fibers; used for insulation, fireproofing, and as a filter medium. Also known as mineral cotton; rock wool; silicate cotton; slag wool.

mineral wool

A wool-like material of fine inorganic fibers such as asbestos or those made from molten rock, slag, or glass; used as loose fill or formed into blanket, batt, block, board, or slab shapes for thermal and acoustical insulation; also used as reinforcement for other materials such as insulating cements and gypsum wallboard.

The researches into dependency of compressive resistance and deformability of mineral wool products on components of microstructure (filament mass of mineral wool and percentage of binder) and structure (horizontally layered, vertically layered, corrugated, mixed orientation of filaments) and the mathematical assessment of these factors according to the received experimental data is the most reliable method for designing and production of mineral wool boards with predetermined (required) strength properties Gnip et al.

The thermal insulation products made of mineral wool depending on the orientation of fibres could be divided into the chaotic (the case when fibres are distributed randomly and in different directions irregularly) and the directional (the case when fibres are distributed in a certain order) [1, 2] in terms of the structure.

IIG manufactures a wide range of insulation products for use in industrial, commercial and fireproofing applications and offers a unique "good, better, best" portfolio of high-temperature insulation, ranging from mineral wool to perlite to calcium silicate.
